(705 ILCS 405/5-601)
    Sec. 5-601. Trial.
    (1) When a petition has been filed alleging that the minor is a delinquent, a trial must be held within 120 days of a written demand for such hearing made by any party, except that when the State, without success, has exercised due diligence to obtain evidence material to the case and there are reasonable grounds to believe that the evidence may be obtained at a later date, the court may, upon motion by the State, continue the trial for not more than 30 additional days.
    (2) If a minor respondent has multiple delinquency petitions pending against him or her in the same county and simultaneously demands a trial upon more than one delinquency petition pending against him or her in the same county, he or she shall receive a trial or have a finding, after waiver of trial, upon at least one such petition before expiration relative to any of the pending petitions of the period described by this Section. All remaining petitions thus pending against the minor respondent shall be adjudicated within 160 days from the date on which a finding relative to the first petition prosecuted is rendered under Section 5-620 of this Article, or, if the trial upon the first petition is terminated without a finding and there is no subsequent trial, or adjudication after waiver of trial, on the first petition within a reasonable time, the minor shall receive a trial upon all of the remaining petitions within 160 days from the date on which the trial, or finding after waiver of trial, on the first petition is concluded. If either such period of 160 days expires without the commencement of trial, or adjudication after waiver of trial, of any of the remaining pending petitions, the petition or petitions shall be dismissed and barred for want of prosecution unless the delay is occasioned by any of the reasons described in this Section.
    (3) When no such trial is held within the time required by subsections (1) and (2) of this Section, the court shall, upon motion by any party, dismiss the petition with prejudice.
    (4) Without affecting the applicability of the tolling and multiple prosecution provisions of subsections (8) and (2) of this Section when a petition has been filed alleging that the minor is a delinquent and the minor is in detention or shelter care, the trial shall be held within 30 calendar days after the date of the order directing detention or shelter care, or the earliest possible date in compliance with the provisions of Section 5-525 as to the custodial parent, guardian or legal custodian, but no later than 45 calendar days from the date of the order of the court directing detention or shelter care. When the petition alleges the minor has committed an offense involving a controlled substance as defined in the Illinois Controlled Substances Act or methamphetamine as defined in the Methamphetamine Control and Community Protection Act, the court may, upon motion of the State, continue the trial for receipt of a confirmatory laboratory report for up to 45 days after the date of the order directing detention or shelter care. When the petition alleges the minor committed an offense that involves the death of, great bodily harm to or sexual assault or aggravated criminal sexual abuse on a victim, the court may, upon motion of the State, continue the trial for not more than 70 calendar days after the date of the order directing detention or shelter care.
    Any failure to comply with the time limits of this Section shall require the immediate release of the minor from detention, and the time limits set forth in subsections (1) and (2) shall apply.
    (5) If the court determines that the State, without success, has exercised due diligence to obtain the results of DNA testing that is material to the case, and that there are reasonable grounds to believe that the results may be obtained at a later date, the court may continue the cause on application of the State for not more than 120 additional days. The court may also extend the period of detention of the minor for not more than 120 additional days.
    (6) If the State's Attorney makes a written request that a proceeding be designated an extended juvenile jurisdiction prosecution, and the minor is in detention, the period the minor can be held in detention pursuant to subsection (4), shall be extended an additional 30 days after the court determines whether the proceeding will be designated an extended juvenile jurisdiction prosecution or the State's Attorney withdraws the request for extended juvenile jurisdiction prosecution.
    (7) When the State's Attorney files a motion for waiver of jurisdiction pursuant to Section 5-805, and the minor is in detention, the period the minor can be held in detention pursuant to subsection (4), shall be extended an additional 30 days if the court denies motion for waiver of jurisdiction or the State's Attorney withdraws the motion for waiver of jurisdiction.
    (8) The period in which a trial shall be held as prescribed by subsections (1), (2), (3), (4), (5), (6), or (7) of this Section is tolled by: (i) delay occasioned by the minor; (ii) a continuance allowed pursuant to Section 114-4 of the Code of Criminal Procedure of 1963 after the court's determination of the minor's incapacity for trial; (iii) an interlocutory appeal; (iv) an examination of fitness ordered pursuant to Section 104-13 of the Code of Criminal Procedure of 1963; (v) a fitness hearing; or (vi) an adjudication of unfitness for trial. Any such delay shall temporarily suspend, for the time of the delay, the period within which a trial must be held as prescribed by subsections (1), (2), (4), (5), and (6) of this Section. On the day of expiration of the delays the period shall continue at the point at which the time was suspended.
    (9) Nothing in this Section prevents the minor or the minor's parents, guardian or legal custodian from exercising their respective rights to waive the time limits set forth in this Section.
